DS90UB933-Q1: the default configuration of TI933 can work normally,is this risky?

Part Number: DS90UB933-Q1


Hello! Our products use TI933, the des is TI954, our board and the TI954 are not configure TI933 through IIC, TI933's IDX and MOD are set by external resistors, and then can be work normally, that is to say, the default configuration of TI933 can work normally. Is this risky? The default configuration of the TI933 will not change after each boot, right?

Thank you!
